摘要

摘要: 依据实测剖面资料和薄片鉴定结果，将龙门山下泥盆统甘溪组谢家湾段确定为以泥质为背景的Ⅰ型混积类型和Ⅱ型混积层序，其Ⅰ型混积类型的形成机理包括间断式和原地式两种混积形式，以风暴流所致的间断式混积为主。相关的混积相可划分为混积滨岸、碎屑混积陆棚和碳酸盐混积陆棚三种混积相类型，以及①滨岸潮缘残积物＋混积潮坪、②混积陆棚泥＋远源风暴流、③混积陆棚泥＋近源砂质风暴流、④混积陆棚泥＋近源混积风暴流和生物滩与点礁四种混积微相类型的沉积组合。其Ⅱ型混积层序可划分出SMST、TST、EHST和LHST四个沉积体系域，各体系域由不同的混积类型、混积序列和混积强度的准层序叠置而成，以SMST和LHST的原地式混积作用最强，TST的间断式混积作用最弱，而EHST具有交替的间断式与原地式叠加混积作用。

Abstract: Based on the data of cross sections and observation of thin sections,the Xiejiawan Member of Ganxi Formation ,Lower Devonian in the Longmenshan is considered to be generated from hybrid type Ⅰsediments dominative of shelf shales. Its genetic mechanisms include the major intermittent mixing mode, which is resulted from the storm flow, and the autochthonous mixing mode. The sedimentary facies of the Xiejiawan Member can be divided into following microfacies, hybrid shore,hybrid clastic shelf, hybrid carbonate shelf,shore peritidal residual + hybrid tidal flat,hybrid shelf shale + distal storm flow,hybrid continental shelf shale intercalated with proximal sandy storm flow,hybrid shelf shale intercalated with proximal sandy hybrid storm flow,and hybrid shelf shale intercalated with organic bank and point reef. Meanwhile, the Xiejiawan Member is characteristic of type Ⅱhybrid sequence and can be classified into 4 depositional system tracts of SMST,TST,EHST and LHST. Each system tract is superimposed by subsequences of different sedimentary sequences,textural styles and hybrid intensity. Among the all above mentioned sedimentary tracts,the SMST and LHST are of the most intensive intermittent mixing and autochthonous mixing,the intermittent mixing of TST is the weakest one,and the EHST is of weak intermittent mixing and autochthonous mixing.
